SMS Message Filtering System Using User Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parents face challenges in monitoring their children's electronic messages in real-time for inappropriate content, as existing monitoring systems do not automatically filter messages and require manual review of vast amounts of data.
Innovation Solution
A message filtering system that automatically filters SMS messages using lists of restricted words, user or device profiles, and ratings, allowing for real-time monitoring and delivery determination based on sender or recipient addresses, with an option for manual review by a secondary receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parents manually review all electronic messages to monitor for inappropriate content, then monitoring accuracy is improved, but time consumption increases significantly
Solution Approach 1:
The patent introduces an automated message filtering system that acts as an intermediary between the message stream and parental review. The system automatically parses messages using restricted word lists, user profiles, and ratings to identify inappropriate content, then presents only flagged messages to parents for review. This intermediary filtering layer maintains monitoring accuracy while dramatically reducing the volume of messages parents must manually examine.
2Productivity
If automated filtering using restricted word lists is implemented, then processing speed is improved, but filtering accuracy deteriorates due to false positives
Solution Approach 1:
The patent employs multiple filtering parameters beyond simple restricted word lists, including user-specific profiles that adapt to individual children's messaging patterns, age-appropriate ratings, and sender/recipient address filtering. By changing and combining multiple parameters rather than relying on a single rigid word list, the system maintains high processing speed while reducing false positives through more nuanced, context-aware filtering criteria.
3Reliability
If real-time message monitoring is implemented, then safety is improved, but system complexity increases
Solution Approach 1:
The patent segments the monitoring system into distinct functional modules: message interception components, automated filtering engines using multiple criteria (word lists, profiles, ratings), and parental notification interfaces. This segmentation allows real-time monitoring to be implemented through coordinated simple actions in each module rather than one complex monolithic system, making the overall system more manageable and easier to deploy while maintaining real-time safety monitoring.

AI summary
In one embodiment of the present invention, a system and method of filtering messages may be provided that includes receiving an SMS message intended for a recipient and receiving a user-restriction profile. The system and method includes determining whether the SMS message contains content that is indicated to be restricted by the user-restriction profile and, in response to the determination that the SMS message contains restricted content, delivering the SMS message to an authorized secondary receiver. Alternatively, in response to the determination that the SMS message does not contain restricted content, the SMS message may be delivered to the recipient.
